Abstract: ABSTRACT OF THE DISCLOSURE            A perineal shield and discharge containment device comprised of a sheet of flexible material adapted for folding along a plurality of pre-established fold lines to provide a folded configuration which will closely conform to the perineal contours of the human body.  The pre-established fold lines radiate outward from a common base point interiorly disposed on the longitudinal center-line of the sheet material.  When folded as prescribed, the sheet material has an upwardly concave configuration in both transverse and longitudinal directions with the deepest point of the concavity origi-nating at the base point.  When the folded sheet material is positioned in contact with the perineum an upstanding anterior portion, comprising the full width of the sheet, covers the pubic area.  From the full width anterior portion the folded sheet tapers back to form a narrow isthmus which fits comfortably between the thighs, then diverges outward to form a full width posterior portion which covers the after-parts of the perineum.

Abstract: ABSTRACT        There is provided the combination of a frame and a collapsible ladder.  The frame defines two spaced-apart horizontal passages in which catch elements are mounted.  Resilient means urge the catch elements toward each other, and manual thumbscrew means are provided to pull the catch elements away from each other.  A collapsible ladder has attachment means at the top by which it can be anchored, and the ladder also includes a containment means constituted by the bottom rung and two upstanding side members which register with all of the remaining rungs.  The upstanding side members have openings at the top into which the catch members extend when in their innermost positions.  Manual release is possible by which the side members become disengaged from the frame, thus allowing the web ladder to fall into a position of use.

Abstract: " 1 "                 ABSTRACT OF THE DISCLOSURE  The invention relates to the formation of a protective skin on blocks of microporous thermal insulation material.          Such material is difficult to protect because the securement of a protective layer by some form of adhesive securement provides only a relatively loose bond.  According to the invention, a laser beam is used to fuse a surface layer of particles in the material to form a protective skin.  The beam may be passed over an otherwise "raw" edge of a block of material, or used also to cut the block from a workpiece while simultaneously forming the skin.  This enables the cutting of accurate shapes either by manual or automatic control of the passage of the beam through the workpiece, the latter much facilitating mass production of relati? complicated shapes.

Abstract: ABSTRACT OF THE DISCLOSURE           The apparatus provides for the automatic uncoupling of a toy semitrailer from a toy tractor truck and provides also for automatic coupling of a toy semitrailer to a toy tractor truck.  The uncoupling utilizes a ramp in a road-way which is inboard of the tractor truck wheels, and this ramp is engaged by the forward dolly wheels on the semitrailer, which dolly wheels arc also inboard of the truck tractor wheels.  The coupling of the toy semitrailer to the toy tractor is achieved by a simple beveled end on the rear of the toy tractor, which backs up to the semitrailer, and the king pin of the semitractor rides up this bevel to the pivot flat area of the tractor to drop into the pivot hole. both operations arc carried out in the same locality by a reciprocating dock which is contacted by the semitrailer during its backing up at the time its dolly wheels ride up the ramp to release the tractor.  After the tractor vehicle departs, a delayed spring action moves the dock forwardly to move the semitractor forwardly off the ramp so that the semitrailer may then be contacted by the tractor backing up to it to connect the two vehicles.

Abstract: ABSTRACT          A device (10) is disclosed for mounting a hearing protector (90) on each side of a hard hat, pressing the hearing protectors at a substantially constant force about the ears and moving them in oppositely incline planes between an operative wearing position (W) and an extended inoperative pressure relieved stored position (R).  Each device comprises support means (20) including a pivot (28) adapted for attachment to and retained to a side of the hard hat (H), by retainer means (30), guide means (40) (50) including at least one incline surface (44) (54) and a key boss (46) (56) projecting into a key hole shape slot (79) in a rigid central end portion (72) of a resilient flexible support arm (70) secured by releasable clamping means (60) When positioned in the elongated part of the key hole slot, the key boss allows limited vertical and angular adjustments of the support arm (70) and unrestricted rotation between operative and inoperative positions can occur only when the support arm is fully extended and an enlarged circular end portion of the key hole slot is aligned with the axis of the pivot stud and key boss of smaller diameter.  Support arm (70) has at least one flexible resilient leg of fixed length extending from the rigid central portion (72) to a fixed pivot axis or point of connection (80) with a hearing protector (90).  Thus, at any given degree of flexure the support arm exerts a substantially constant resilient force and extending and rotation of the support arm along the incline plane to the inoperative stored position shifts the arm and protector outwardly from any substantially pressure contact with the side of the hat to allow the arm and protector to recover and return to an unflexed natural state.
